Andriy Yermak was a constant, looming presence in Ukraine's government - a seemingly immovable figure on the political stage.
Despite his towering frame, you might not always have spotted him. Yet, wherever President Volodymyr Zelensky was, Yermak was often not far away.
As his chief of staff, Yermak wielded enormous power at the top of government and was even trusted to negotiate on Ukraine's behalf at peace talks with the US.
But as his influence grew, so did public resentment of the power this unelected official held. His political career came to an abrupt end on Friday, hours after anti-corruption investigators raided his home in Kyiv.
Yermak and Zelensky first met in 2011 when the former was an intellectual property lawyer and the latter a TV producer.
